PHONOGRAPHIC AUTOMOBILE-ALARM.

Specification of Letters Patent.

Patented A112. 29, 1911.

Application filed October 24, 1910. Sei'ial N0. 588,643.

To all whom it may concern:

' Be it known that I, JOSEPH H. ERICKSON, a citizen of the United States, residing in the city and county of San Francisco and vState of California, have invented new and luseful Improvements in Phonographic Automobile-Alarms, of which the following is a specification.

This invention relates to a phonographic automobile alarm, and -particularly pertains to an automatic repeating' attachment for phonographs and the like.

It is the object of this invention to provide an automobile alarm which is operated by a phonograph so as to produce spoken or `musical warnings, and to provide automatic means by which the warnings may be controlled and given repeatedly, if desired.

A further object is to provide mechanical means by which quick action of the phonograph will be effected, both at the beginning and at the termination of thealarm, thus insuring the warning being quickly and sharply given and instantlycut ofi' at its completion.

The invention consists of the parts and combination and construction of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which- Y Figure 1 is a side view of the invention with parts broken away. Fig. 2 is a front view of' the same. Fig. 3 is a plan view of the carriage actuating mechanism. Fig. 4 isa perspectivey view of the carriage tripping device. Fig. 5 is a view showing the invention as applied.

In the drawings A represents the ordinary cylindrical phonograph record which is mounted to revolve with a drum 2 secured to a shaft 3 supported at each end in suitable bearings 4, mounted on a base plate B, as is common in phonograph construction. The

' shaft is rotated by means of a belt 5 which f a wheel 7 on a shaft 8 located. beneath the plate B and parallel with the shaft 3. The shaft 8 is supported at both ends on a rock able frame 9, pivoted at 140, some distance to the rear of the shaft 8, and is adapted to be rotated by means of a friction drive commeans of a small electric motor 14 disposed beneath the plate B; the' motor' 14 being thrown in and out of operation synchronously with the engaging and di'sengaging of the friction pulley 11 with the pulley 12.

lThis is 'accomplishedby the following mech# an1sm:-'An arm 15 extending beneath the frame 9 and pivoted at 16 cont-acts the underside of the outer end of the frame andv sustains it in its normally up ermost position with the pulley 11 out o contact with the pulley 12; the arm 15 being caused to continually press upward to lift the frame by means of a spring 17, which bears against the underside of the arm 15, as shown ,in Fig. 1. The outer end of the arm 15 projects beyond the end of the frame 9 and is provided with a contact plate 18 which connects with one pole of a battery 19, the other pole of which connects with one terminal of the motor 14. A knife 2O is disposed beneath the arm 15. in line with the contact plate'18 so as to be thrown into contact with the latter as the outer end of the arm 15 is pulled downward, as later described; the knife 20 being electrically connected with the other terminal of the motor 14. A cord 21 is attached to the outer end ofthe lever 15 and is intended to be connected to any suitable device or means for exerting a suiiicient pull thereon in opposition to the spring 17 to throw the Contact plate 18 into contact with the knife 20, and thus complete a circuit-y from the battery 19 to actuate the motor 14 and at the same time permit the frame 9 to drop downward and cause the'pulley 11 to be engaged by the pulley 12 to rotate the drum 2 and record A.

In Fig. 5 the cord 21 is shown as connected to a lever 22 which is adapted to be actuated by means of a push button or tread 28, which may be disposed at any convenient point remote from the mechanism just: de-

scribed.. 1 passes around a wheel on theshaft 3 and The shaft 3 carries a pinion 24 on one end which enga-ges with an idle gear 25 `which in turn meshes with a gear 26 on a threaded shaft 27, so as to rotate the latter when the shaft 3 is revolved as before described.

A carriage 28 carrying the usual sound box 29 and needle 30 of a phonograph is slidably mounted on a shaft 31 extending parallel with and a little above the threaded. shaft 2T, an extension 2S on the carriage 28 projecting beneath the shaft 27 and threaded at its point of Contact therewith, so that when engaged by the threaded shaft 27 the carriage 28 will be caused to move in one d1- rection across the record A, as is well known in phonographs of this type. Normally the needle 30 is held out of cont-act with the record cylinder A, and the carriage 28 out of engagement vwith the threaded shaft 27, by means of a standard 32 mounted on the frame 9, the upper` end of which is turned to extend parallel with the record A and to form a support upon which a projection on the outer end of the frame 28 is adapted to rest. From this it will be seen that when the frame 9 is allowed to drop downward bya pull on the cord 21, the needle 30 will be thrown into Contact with the record A, so as to vibrate the diaphragm in the sound box 29 and reproduce the Sounds originally recorded on the cylinder A; the carriage 28 carrying the needle 30 and sound box 29 being moved along by the threaded shaft 27, which normally engages the carriage when the needle 30 contacts the record A.

By attaching the mouthpiece of the sound box 29 to an automobile horn 33 by a flexible tube 34, as shown in Fig. 5, and mounting the whole device upon an, automobile an effective alarm or warning is obtained, which may be operated at will by pressing upon the button 23. The exact expression of warning to be given may be anything suitable which may be produced by phonographic record, such as for instance, Get out of the way, a bugle call or the like.

As it may be desired to give continuous alarms and constantly repeat -the warnings, means are provided for automatically returning the carriage 18 instant-ly to its normal position as soon as it has passed the length of the record A, so as to repeat the alarm as long as the arm 15 and frame 9 `are pulled down. This is accomplished by mounting a disk 35 on the front end of the carriage 28 in front of the standard 32, a pin 36 on the back of the disk projecting above a vertically disposed plate 37 on the base plate B; and having a linger 38 extending downward between two adjustable stops 39`40, as shown in Figs. 2 and 4. When the outer end of the carriage 28 is in its lowermost position with the needle 30 in contact with the record A and the projection 28 engaged by the threaded shaft 27, the pin 36 will Contact the plate 37 so that when the linger 38 comes in contact with the stop 40 as the carriage 28 moves forward, the disk 35 will be rocked on its bearing with the pin 36 acting' as a cam on the plate 37 to raise the outer end of the carriage 28 and release the threaded projection 28 from the shaft 27 whereupon a spring 41 on the shaft 3l will return the carriage 28 to its starting position.- A spring 42 engages a notch 43 on the disk to retain it in the position set by the stop 40 until the carriage 28 has completed its return, whereupon a lip 39 on the stop 39 is encountered by the linger 38 which acts to restore the disk 35 to its normal posltion and allows the front end of the carriage 28 to drop down as before, to be again carried across the record A.

The operation of the invention is auparent from the foregoing description; itv .eing readily seen that when it is desired to give a phonographic alarm, a pull on the string 21 will allow the carriage 28 to gravitate downward to throw the needle 30 into operative engagement with the record A, and at the same time start the motor 14 which revolves the record A and moves the carriage 28 forward as before described, and that as long as the arm 15 is down by virtue of the ull on the string 21 the motor 14 will contlnue to act and the carriage will repeatedly travel back and forth across the record by means of threaded shaft 27, the trip disk 35 and its co-acting parts and the spring 41; and that as s oon as the pull on the string 21 is released the carriage 28 will be lifted up by the standard 32 and returned to its normal position by the spring 41.
